A Hardware-aware and Stable Orthogonalization Framework
Nils-Arne Dreier, Christian Engwer
The orthogonalization process is an essential building block in Krylov space methods, which takes up a large portion of the computational time. Commonly used methods, like the Gram…
Hardware-Oriented Krylov Methods for High-Performance Computing
Nils-Arne Dreier
Krylov subspace methods are an essential building block in numerical simulation software. The efficient utilization of modern hardware is a challenging problem in the development o…
Strategies for the vectorized Block Conjugate Gradients method
Nils-Arne Dreier, Christian Engwer
Block Krylov methods have recently gained a lot of attraction. Due to their increased arithmetic intensity they offer a promising way to improve performance on modern hardware. Rec…
The DUNE Framework: Basic Concepts and Recent Developments
Peter Bastian, Markus Blatt, Andreas Dedner +9
This paper presents the basic concepts and the module structure of the Distributed and Unified Numerics Environment and reflects on recent developments and general changes that hap…
A high-level C++ approach to manage local errors, asynchrony and faults in an MPI application
Christian Engwer, Mirco Altenbernd, Nils-Arne Dreier +1
C++ advocates exceptions as the preferred way to handle unexpected behaviour of an implementation in the code. This does not integrate well with the error handling of MPI, which mo…
